UIT, as part of General Atomics Group, is an international innovative engineering and consulting company specialized in mineral exploration and processing of technology metals.

About us

UIT is a competent partner for planning, evaluation, construction, and realization of projects to the benefit of our environment. As part of the General Atomics Group, our interdisciplinary team works on behalf of our clients in Germany, Europe and worldwide.

We are experienced in solving hydrometallurgical, geochemical and process engineering challenges. UIT is specialized in the processing of minerals containing technology metals associated with NORM and offers technical and management support for exploration and projects portfolio.

Our experts have designed and successfully applied entire hydrometallurgical processing chains for conventional ore processing operations as well as in-situ recovery (ISR). Industrial metallurgical processing options are investigated from lab- to pilot-scale and are simulated by chemical processing models for up-scaling.

UIT develops and actively applies dedicated software tools for computer simulations in hydrology, geochemistry and chemical processing.

Products and Services

UIT offers consulting, full-scale engineering, manufacture and implementation of technical facilities, and turn-key plant construction in the business areas of Mineral Resources, Environmental Monitoring and Water Technology.

UIT operates two technical centers for lab and pilot scale testing which are also specialized in the processing of minerals containing technology metals associated with NORM (Naturally Occurring Radioactive Material).
Services:

  • Exploration – geophysics – economic geology

  • Feasibility studies towards engineering

  • Expertise in unconventional mining methods including in-situ recovery (ISR)

  • Mineral processing / NORM separation (removal of natural radioactivity) – process design

  • Metal separation / refining – from test work to engineering

  • Mining/industrial water treatment

  • Metallurgical process simulation / modeling, in particular, IX, IEX, RIP, SX, …

  • Environmental monitoring in active mining and remediation applications

  • Environmentally compliant mining and remediation
Extractive (Hydro-)Metallurgy and Mineral Processing

UIT provides expert know-how on the relevant
technologies and licensing steps required for extracting
technology metals (REE, PGE, etc.) and for separation
of associated naturally occurring material (NORM) and
processing of radioactive elements such as uranium
(U), thorium (Th), and their decay products. Our team
covers the entire hydrometallurgical processing chain
including technologies like flotation, leaching, IX/RIP,
IEC, SX, full-scale down-stream processing including
separation/refining.

Column Leach Test Facility

The column leach test facility (saturated flow) is
designed according to international standards,
operating a 3-channel system either in horizontal or
vertical flow. Operational parameters are in accordance
to realistic ISR wellfield conditions (aquifer temperature
and pressure, pore volume exchange rate) and are
monitored by real-time data logging/control. Drill cores
and bulk samples can be tested and analyzed for ISR
feasibility and performance.

News & Innovations

R&D: Innovative recovery methods for Indonesian deposits

UIT is part of the publicly funded StratOre project. This project investigates the efficient and sustainable extraction of strategic elements from Indonesian ore deposits.

With our partners, we are developing new processing and exploration concepts for the efficient extraction of strategic elements from Indonesian ore deposits.

In doing so, we are focusing on new extraction methods for strategically valuable elements: PGEs (Platinum Group Elements), Co, Ni and Sc from an Fe-Ni laterite.

Laterites (highly weathered rocks) form excellent exploration targets as a natural source and are often located in tropical regions. By working with Indonesian companies, research on current deposits is made possible and a trusting cooperation with international partners is established. Due to UIT's many years of experience and expertise in this field, hydrometallurgical tests are planned at the Dresden site and carried out in a UIT pilot plant in the company's own technical center.

Rare Earth Element Separation

UIT successfully operated two hydrometallurgical pilot plant campaigns in Germany. The results, indicate the successful extraction of Nd/Pr and other REE, contained in a high-purity rare earth oxide (REO). UIT is currently working on the verification in small industrial scale within the DOE (U.S. Department of Energy) founded project for facility design and engineering in preparation for the construction and operation of a Rare Earth Element (REE) Separation and Processing Demonstration Plant.

It utilizes the enhanced proprietary technology to produce several products- a high-purity neodymium/praseodymium (Nd/Pr) oxide, lanthanum (La) oxide, and a mixed mid-and heavy rare earth concentrate. The enhanced process is expected to significantly reduce process steps and operating costs as well as further reduce environmental impacts and associated costs.

OreLog

UIT’s geophysical borehole logging tool OreLog constrains petrophysical and geochemical parameters of the ore body and the host rock near real-time and, hence, it is economically highly interesting compared to drill core interpretation.

OreLog provides accurate elemental concentrations used to deduce mineralogy and ore grade and furthermore yields petrophysical parameters including porosity, permeability and hole inclination. This allows you to make the next key exploration decision.

Orelog’s petrophysical parameters provide an important link to seismic survey data, as they allow to constrain interval velocity models and therefore to generate 3D models of the ore body.

Through a major upgrade of the tool in 2022, Orelog’s detection limit could be significantly lowered for target elements such as Fe, Ca, Si, Mg, S, Mn and soon Al. The launch of OreLog is planned for 2023. Get in touch!
